Hi,
Could you please try to set the HostsInReserve parameter of the
power_saving policy to 1? This should always keep 1 empty host (with no
running vms) to be ready in case the others are over utilized. If there are
more empty hosts, they should be put into maintenance or shut down, if
there is no empty host, a host should be put back online from maintenance
or down state.
Regards,
Lucia

Hi List,
I'm using the power_saving schedule to minimise the number of physical
hosts which works as expected when scaling in, however it doesn't appear to
ever scale out.
I've tried setting the minimum and maximum RAM and lowering the
HighUsage (Utilization in American) percentage but it never starts another
host.
If I don't change the scheduling policy and manually start another host,
it gets powered off by the scheduler before any resources get allocated to
it.
Am I missing a setting or is it just a MASSIVE flaw in the scheduler?
